Abstract: A warp stop-motion mechanism including a plurality of electrodes and means supporting the electrodes in a common plane. A drop wire is provided for each warp yarn and the warp yarns support the drop wires about the electrodes in normal operation. A control bar is provided at a lower elevation than the electrodes and is in continuous engagement with the warp yarns during normal operation of the loom to prevent repetitive contact of the electrodes by the warp yarns and drop wires. Means are provided for adjusting the warp stop-motion mechanism longitudinally, transversely, and vertically.

Abstract: The invention comprises a fully adjustable and pivotal support for a warp stop-motion which may be finely adjusted to its optimum operable position and then pivoted upwardly and out of the way when desired, as while changing the warp beam, and instantly and accurately retured to said optimum operating position by means of a positive stop which positions the warp stop-motion mechanism in said optimum operative position automatically without further attention by the operator except to tighten the few bolts necessary to hold the warp stop-motion mechanism in said optimum operating position.
